Step 1: Determine the UTF-8 encoding bit layout
The character ℟ has the Unicode code point U+211F. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800to0xffff.
Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format:1110xxxx 10xxxxxx 10xxxxxx
Where thexare the payload bits.UTF-8 Encoding bit layout by codepoint range Codepoint Range Bytes Bit pattern Payload length U+0000 - U+007F 1 0xxxxxxx 7 bits U+0080 - U+07FF 2 110xxxxx 10xxxxxx 11 bits U+0800 - U+FFFF 3 1110xxxx 10xxxxxx 10xxxxxx 16 bits U+10000 - U+10FFFF 4 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx 21 bits Step 2: Obtain the payload bits:
Convert the hexadecimal code point U+211F to binary:
00100001 00011111. Those are the payload bits.Step 3: Fill in the bits to match the bit pattern:
Obtain the final bytes by arranging the paylod bits to match the bit layout:
11100010 10000100 10011111

Description
The Unicode character U+211F, also known as RESPONSE, is a specialized typographical symbol primarily used in mathematical notation and logical expressions in digital text. It plays a crucial role in representing a binary response or negation in certain contexts. In particular, it is utilized to denote the result of applying the NAND operation between two binary values. This operation is fundamental in digital logic and computer science, serving as a building block for more complex operations and circuits. The character's relevance extends beyond mathematics and programming, as it can also be found in linguistic contexts where it signifies a response or reaction to a statement or question, although this usage is less common. Overall, U+211F is an important character for accurate communication in various technical domains.
